Women in Love is a novel by British author D. H. Lawrence published in 1920. It is a sequel to his earlier novel The Rainbow (1915), and follows the continuing loves and lives of the Brangwen sisters, Gudrun and Ursula. Gudrun Brangwen, an artist, pursues a destructive relationship with Gerald Crich, an industrialist. Lawrence contrasts this pair with the love that develops between Ursula and Rupert Birkin, an alienated intellectual who articulates many opinions associated with the author. The emotional relationships thus established are given further depth and tension by an intense and physical attraction between Gerald and Rupert. The novel ranges over the whole of British society before the time of the First World War and eventually ends high up in the snows of the Tyrolean Alps.

As with most of Lawrence's works, Women in Love caused controversy over its sexual subject matter. One early reviewer said of it, "I do not claim to be a literary critic, but I know dirt when I smell it, and here is dirt in heaps — festering, putrid heaps which smell to high Heaven."

In 1998, the Modern Library ranked Women in Love 49th on its list of the 100 best English-language novels of the 20th century.

Ursula and Gudrun Brangwen are two sisters living in the Midlands of England in the 1910s. Ursula is a teacher, Gudrun an artist. They meet two men who live nearby, school inspector Rupert Birkin and coal-mine heir Gerald Crich. The four become friends. Ursula and Birkin become involved, and Gudrun eventually begins a love affair with Gerald.

All four are deeply concerned with questions of society, politics, and the relationship between men and women. At a party at Gerald's estate, Gerald's sister Diana drowns. Gudrun becomes the teacher and mentor of his youngest sister. Soon Gerald's coal-mine-owning father dies as well, after a long illness. After the funeral, Gerald goes to Gudrun's house and spends the night with her, while her parents sleep in another room.

Birkin asks Ursula to marry him, and she agrees. Gerald and Gudrun's relationship, however, becomes stormy. The four vacation in the Alps. Gudrun begins an intense friendship with Loerke, a physically puny but emotionally commanding artist from Dresden. Gerald, enraged by Loerke, by Gudrun's verbal abuse, and by his own destructive nature, tries to murder Gudrun. After failing, he retreats back over the mountains and falls to his death in the snow.
